Theory:

And true to his word, that little elf began to do Patrick’s homework. Except there was one glitch. The elf didn’t always know what to do and he needed help. “Help me! Help me!” he’d say. And Patrick would have to help — in whatever way.“I don’t know this word,” the elf squeaked while reading Patrick’shomework. “Get me a dictionary. No, what’s even better, look up the word and sound it out by each letter.”
Explanation:

And keeping his promise, the elf (supernatural human) started his work. But, he needed help as he didn’t know anything about the subjects. He asked Patrick to help him. Then Patrick had no other choice but to help him. Suddenly while doing Patrick’s homework  the elf would  say aloud that he doesn’t know the meaning of  a particular word, so to tell him a dictionary meaning or something that can help him to identify the each letter and word.
